How to copy the rest of lines of a file to another file












2















I have the string xyz which is a line in file1.txt, I want to copy all the lines after xyz in file1.txt to a new file file2.txt. How can I achieve this?



I know about cat command. But how to specify the starting line?






files grep cat file-copy file-transfer

    Do you want to include that xyz line or exclude it from being copied ? Also, what happens if you have multiple lines matching xyz ?

Using GNU sed



To copy all lines after xyz, try:



sed '0,/xyz/d' file1.txt >file2.txt


1,/xyz/ specifies a range of lines starting with the first and ending with the first occurrence of a line matching xyz. d tells sed to delete those lines.



Note: For BSD/MacOS sed, one can use sed '1,/xyz/d' file1.txt >file2.txt but this only works if the first appearance of xyz is in the second line or later. (Hat tip: kusalananda.)



Another approach, as suggested by don_crissti, should work for all sed:



{ printf %s\n; cat file1.txt; } | sed '1,/xyz/d' >file2.txt


Example



Consider this test file:



$ cat file1.txt

a

b

xyz

c

d


Run our command:



$ sed '1,/xyz/d' file1.txt >file2.txt

$ cat file2.txt

c

d


Using awk



The same logic can used with awk:



awk 'NR==1,/xyz/{next} 1' file1.txt >file2.txt


NR==1,/xyz/{next} tells awk to skip over all lines from the first (NR==1) to the first line matching the regex xyz. 1 tells awk to print any remaining lines.

With ed:



ed -s file.txt <<< $'/xyz/+1,$w file2.txt'


This sends one (ranged) command to ed: from the line after (+1) the one containing xyz until the end of the file ($), write those lines to file2.txt.

    There is also csplit :



    csplit -s file1.txt %xyz%1

      $ sed -n '/xyz/,$p' file.txt > file2.txt


      With -n we prevent sed to print every line. With $ means end of file end p stands for print line. So /xyz/$p means: If a line matches xyz print it until the end of the file.

      • This would also print the line matching xyz, not from the line after.
